HENRY MONROE MORRIS, OF MIDDLETOWN, CALIFORNIA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 364,598, dated June 7, 18,87.

' Application filed March 21, 1887. Serial No. 231,737. (No model.)

To 00 whom it may concern.-

Be it known thatI, HENRY MONROE MOR- RIS, a citizen of the United States, residing at Middletown, in the county of Lake and State of California, haveinvented a new and useful Improvement in Automatic Gar- Couplings, of which the following is a specification.

My invention relates to automatic car-coup: lings; and it consists in certain novel features, hereinafter fully described, and then pointed out in the claims.

In the annexed drawings, which fully illustrate my invention, Figure l is a vertical 10ngitudinal sectional view of my improved caru coupling, the link being shown in position as coupled, and the position of the parts whenuncoupled being indicated by dotted lines. Fig. 2 is a vertical transverse section, and Fig. 3 is a detail perspective View of the gravitytumbler or pin-support.

Referring to the drawings by letter, A designates the draw-head, secured to the car in the usual manner. The draw-head is provided with the usual openings for the reception of the coupling-pin, and in its upper side I provide the transverse grooves or notches B, which extend from the opposite sides of the hole or opening in the top of the crossbar. These notches or grooves B receive the ends of the gravity-tumbler or pin-support, and thereby pivotally support the same. The gravity-tumbler consists of a U-shaped frame, 0, having the upper ends of its arms bent outward to form trunnions D, which rest in the notches or grooves B in the top of the draw-head. Depending from the crossbar E of the U shaped frame and formed integrally therewith is a trigger, F, which curves backward from the frame, and is adapted to be struck by a link entering the draw-head, as will be presently more specifically set forth. In order to prevent the tumbler being forced out its supports in the draw-head, I provide the retaining-block G, which is secured on the top of the draw-head in any desired manner aud'fits over the trunnions D of the tumbler, thereby effectually retaining them in the groovesor notches, as will be readily understood. This retaining-block G is provided with an opening near its forward end, which aligns with the opening in the upper part of the draw-head, andis adapted to receive the coupling-pin and hold it in a vertical position while waiting to be coupled.

The construction of my device being thus understood, its operation is as follows: The normal position of the tumbler is that shown in dotted lines in Fig. 1, viz., with its crossbar directly under the opening or pin-hole in the upper side of the draw-head. The pin is inserted through said opening and its lower end will rest on the cross-bar of the tumbler. While in this position if the coupling link be made to enter the draw-head, it willstrike the trigger of the tumbler and force it backward,

thereby rocking the support of the pin from. The pin will consequently fall,passunderit. ing through the link, and the coupling will be completed. When it is desired to uncouple the cars, it is necessary only to raise the pin, when the link will be withdrawn by the receding car and the tumbler will automatically swing forwardinto position to receive the pin.

It will be observed that my device is entirely automatic in its actions and can be operated without necessitating the attendants going between the cars and thereby endangering his life. The pin, can be raised by means ofa chain running to the top or side of the car.

My device is cheap, simple, and efficient,

and its advantages are obvious.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, with the draw-head having" the transverse notches in its upper side, of the pin-support having trunnions resting in said notches and a retaining-block secured upon the draw-head over the transverse notches, whereby the trunnions of the pin-support will be held therein, substan-' tially as specified.

2. In a car-coupling, the combination,with the draw-head having transverse notches in its upper side, of the Ushaped pin-support having the ends of its arms bent outward and fitted in said transverse notches, and having atrigger depending centrally from its crossbar and formed integral therewith, and a retaining-block secured upon the draw-head over the transverse notches, substantially as specified. e In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
